McLaren Automotive has released pictures and some details of the Mclaren 650S, its fastest production series supercar yet, ahead of its official unveil at the upcoming Geneva Motor Show 2014.

Available as a hardtop or as a convertible, the 650S is so called because it has 650PS (641bhp) on tap and it is therefore Sporting in its nature.

So much so that McLaren claims the car will redefine the high performance supercar segment. That’s an extremely big boast, but looking at what the company has achieved with the F1, Mercedes-McLaren SLR, 12C and P1, McLaren clearly isn’t in the business of hyperbole.

The car is based on the McLaren 12C but its looks are more in line with the current range-topping P1 hypercar, while performance falls in between.

McLaren has confirmed that the car has a twin-turbo V8 engine that is good for 0-62mph (100km/h) in just 3 seconds, a 0-125mph (200km/h) time of 8.4 seconds. And of course, as is now obligatory for all self-respecting supercars, a top speed in excess of 200mph.

Although the car is based on the existing 12C, 25 percent of its components are new and many of the improvements made to the car’s handling, aerodynamics and engine are a result of developing the P1.

As such, the standard cabin is a big improvement, with Alcantara trim as standard and a better multimedia interface that offers satnav, digital radio and full Bluetooth smartphone connectivity.

It also gets carbon ceramic brakes at no extra charge in order to create an interior environment on a par with an executive sedan, albeit one that, when dropped into track mode, could set a new record at the Nurburgring.

The hardtop coupé version will cost £190,000 ($300,000). That’s £20,000 more than the 12C, but still £600,000 less than the P1 which is sold out.
